How Installing Energy-Efficient Windows in Lakewood Saves You Money
There are several perks of upgrading to energy-efficient windows. Some reasons you may want to consider making the change are the following:
- Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its value, especially if you have an older home.
- Save money on power bills: Because energy-efficient windows decrease the amount of energy used to heat or cool your home, the switch can help you save about $443 annually on your energy bills in Lakewood.
- Decrease your carbon footprint: Decreasing how much energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by about 460 pounds.
- Protect your valuables from fading: When you upgrade to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will fade less due to their ability to filter out harmful UV rays.
Estimated Cost of Window Replacement in Lakewood
When looking into window installation, each company provides varying services and costs. Let's go over some average costs and services.
How Much Do New Windows Cost?
According to our research, the average cost of installing a single window is around $600. However, window replacement costs can range from $200 to $1,200 per window. This is because the cost of window installations are based on a variety of factors specific to your home, such as the size, material and number of windows you need to replace, as well as where your property is located.
With windows, efficiency is one of the most important factors for most homeowners. Efficient windows may cost more upfront, but by increasing the efficiency of your home — particularly during the summer and winter — they can provide many years of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Lakewood homeowners $443+ a year after replacing single-pane windows.
Another factor that affects the total cost is the material of the frame you select. Aluminum frames are generally the least pricey and are sturdy and relatively maintenance-free, but they offer poor insulation. On the other hand, wood frames are the most expensive, as they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.
What Services do Window Installers Offer?
Generally, there are two kinds of window installation services you can get: full-frame and pocket installations.
A full-frame installation replaces the full window, including the sill, frame, trim and the window panes. Because this type of installation requires more time, it will cost more than a pocket installation. Pocket installations (also known as retrofits) are when you replace a window within its existing frame. Pocket installations are simpler and won't cost as much, but you can't do this type of installment if you have any pre-existing rot or water damage.
If you're not sure which window installation service you should get, your installer should be able to help you out. Generally, the decision is influenced by factors like the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Lakewood
In our hunt to find the most reliable, eco-friendly window installers in Lakewood, EcoWatch assessed many companies before settling on these. We have decided to evaluate the top window installation companies in Lakewood primarily based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows have been shown to lower electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
This one is self-explanatory, but we've chosen to highlight window installers that serve the Lakewood area so you can find the best window installation company near you.
Work Quality
We're certain that you're looking for professionals who do a great job installing windows. We've vetted each company included on this list to ensure its technicians are well-qualified and that the company has gotten lots of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed trends in recent customer feedback to determine the companies with the most customer satisfaction. Customer satisfaction might be the factor we place the most value on, as it reflects the quality of services across most other categories, including warranty, quality of parts, professionalism, cost, quality of installation and more.
Cost
This one is a give-and-take: similar to other services, cheap window installers are not going to provide the most quality service. On the other hand, we want to ensure we're highlighting companies that offer a wide range of price and financing options so they're accessible to most homeowners.
Warranty
Protecting your investment in new windows is important to many homeowners. That's why window installation companies that give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have been in the industry for quite some time. Window installers that have more years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.
Lakewood, CO Window Replacement FAQs
How much should window installation cost?
The national average cost to install one window is about $600 but can range from $200 to $1,200, based on a few different factors. The price is generally influenced by the location of your property, the type and material of the window and the size of the window. Also, remember that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.
What kind of window is the best for energy efficiency?
A window's energy efficiency is influenced by several factors, such as the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are typically the most energy-efficient and are certified by the U.S. Department of Energy.
Can I install my own windows?
Even though it is possible to install your own windows, doing so requires a lot of time and experience with home improvement projects. Hiring a professional can help ensure that the job is done properly and that you can avoid spending the time and effort of doing it yourself.
How long does window installation usually take?
Each window takes around 30 minutes to install depending on the type of window. However, the window installation can take two days or more if you have a lot of windows that must be installed.
How often should you replace your windows?
Windows typically have a lifespan of about 20 to 30 years, but anytime you see damage on your windows, it's a good time to have an expert take a look at them to determine if they need any repairs or replacements.
